ROAS & Digital Marketing Calculator

Calculate your Return on Ad Spend and Campaign Profitability

ROAS (Ratio): 0.00:1
ROAS (Percentage): 0%
Net Profit: $0.00
ROI (Return on Investment): 0%

What is ROAS?

Return on Ad Spend (ROAS) is a key marketing metric that measures the amount of revenue your business earns for every dollar it spends on advertising. Unlike general ROI, ROAS focuses specifically on the effectiveness of a particular campaign, ad group, or keyword.

ROAS = Total Revenue / Total Ad Spend

Understanding the Results

To interpret your ROAS, consider these benchmarks:

  • 1:1 ROAS: You are breaking even on ad spend (but likely losing money after product costs and overhead).
  • 4:1 ROAS: Generally considered a successful benchmark for e-commerce businesses.
  • 10:1 ROAS: Exceptional performance, indicating a highly profitable campaign.

ROAS vs. ROI: What's the difference?

While ROAS measures gross revenue generated per dollar spent on ads, ROI (Return on Investment) accounts for all expenses, including the cost of goods sold (COGS), shipping, and labor. ROAS tells you if your ads are working; ROI tells you if your business is making money.

Practical Example

If you spend $2,000 on Google Ads and generate $10,000 in sales:

  • ROAS: $10,000 / $2,000 = 5.0 (or 500%)
  • Meaning: For every $1 you spent, you earned $5 in revenue.
function calculateROAS() { var spend = parseFloat(document.getElementById("adSpend").value); var rev = parseFloat(document.getElementById("revenue").value); var container = document.getElementById("resultContainer"); if (isNaN(spend) || isNaN(rev) || spend <= 0) { alert("Please enter valid positive numbers for Ad Spend and Revenue."); return; } // Logic var roasValue = rev / spend; var roasPercentage = roasValue * 100; var profit = rev – spend; var roi = (profit / spend) * 100; // Display document.getElementById("roasRatio").innerText = roasValue.toFixed(2) + ":1"; document.getElementById("roasPercent").innerText = roasPercentage.toFixed(0) + "%"; document.getElementById("netProfit").innerText = "$" + profit.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2}); document.getElementById("roiVal").innerText = roi.toFixed(2) + "%"; container.style.display = "block"; // Smooth scroll to result on mobile if(window.innerWidth < 600) { container.scrollIntoView({ behavior: 'smooth' }); } }
